oll'whom it may cancer .1. ling: at Wainwright, Province of Alberta, and Dominion of (Janada, have invented new and useful: Improvements in Wheeled i ehicles, of which the following is a specification. l 4 i My invention which will be hereinafter fully set forth and claimed relates to wheeled road vehicles and especially to such that are intended to travel upon soft ground.

The objectof my invention is a device I providing an automatically movable track upon which the wheels of the vehicle travel.

It attain this object by means of an auxiliary wheel, or, more strictly speaking, of awheel rim, with. broad faces and independent gear and rotation, within which the vehicle wheel rotates, traveling on the internal surface of said rim.

Figure 1, is a plan of a. wagon fitted with my device, parts being in section to show the construction. Fig. 2, is an elevationof the same, also having parts in section. "Fig. 3,

is a front elevation of the same, also having parts in section and Fig. 4:, is a section on line 4 4, Fig. 1.

A is the front axle tree, A ,-the rear axle tree, B the bolster, B theking bolt and C the box of an ordinary wagon; the pole is not shown, nor a reach for which latter't-hev wagon box is doing service.

W W are the front wheels and l W the rear wheels. They' are of-the ordinary construction, except that the wheel rims w, or tires have a central groove, 2, and their hubs, 2.0 are mounted on the axles in the ordinary way, a being the axle pins or journals.

1) are broad wheel rims, of greater diameter'than the wheels W VV having inner side fianges, d, and a central tongue or ridge,

adapted to engage the groove '2 in the wheel rim. These rims are broad and the space between the flanges a? is under than the rim of the wheels W and W, as shown 111 Figs. 1 and 3.

Arms, al on one side,the outer face, of the rim, carry a hub-like construction, (Z some distance from the face of the wheel hub w (so as to leave playbetween them) and to this rim-huh (Z is secu'reda stud d acting as an axle pin. Each of these axle pins, 63

is ournal'ed a block, E, having its topand bottom grooved longitudinally (see Fig. 3}. This block carried in a forked term, if, 1Q

posed longitudinally, the-tines, ffof which engage the grooves in the block and allow the latter a longitudinal movement. The arm F iscarried at its rear end upon a square-sectioned bar, l h s'ecnred'by arms, I, parallel to the axle tree; r rs this arm F must have freedom to oscillate, it is mounted upon said bar by a Square eyedcircuIar bush, 1. Said arm passes through a yoke,

. G, which isslotted to allow vertical oscillating movement to said arm, as shown in Fig. 2.

The yoke G is carried by two arms (l-"x G one on each side of the arm F, mortised into said yoke and mounted at the other end upon the square ha r H.

At the rear axle the bar H is in one piece, running through from one side to the other and carrying the arms F and G at each end, but atthe front axle the bar H is in two lengths, so to allow a medial gap for a reach and the like. The arms I are rigidly secured to the axles, holding the bar H rigidly against sagging and torsionally. It will be observed that the arms 1, bars H and arms F and G with yokes G and blocks E form the support of the auxiliary Wheels D,

' which, with their axle pins (Z rotate in the blocks E. The yokes G are held rigidly by the arms G on the bars H, while the hub of the arm F is allowed to turn on the square bar by the bush f and the forked ends f are free'to move vertically, their movement being limited by the slot in the yoke G.

Again, the auxiliary wheels 1) have a certain amount of longitudinal I freedom, as the block E may slide in the forks of the arms F. They are mere shells and carry no part of the weight of the wagon. The road wheels W and W are never in contact with the ground or road surface, but move on the inner surface of the rims ofthe auxiliary wheels, as on a track, while the exterior broad surface of the latter isin contact with the ground or road surface. As the wheels .W and -W rotate, they rotate the auxiliary Wheels D, thus continually putting. down new track in front of them and taking it up at the rear and providing a smooth surface (the inner face'of the rim D) for its travel.

I claim as my invention: 1. In a wheeled vehicle, the combination with the axles and wheels. of longitudinal arms projecting rearwardly and secured rigidly to the axles, a transverse bar'parallel to each axle and carried rigidly by sa d arms, a pair of arms held torsionally on the outer ends of-said bars, outside of the wheels and. projecting forwardly,- a slotted yoke carried by said arms, an arm between each pair of said yoke arms mounted rotatively on said transversebar iand passing through the slot of said yoke and having a forked end, a

substantially as set forth.

2. In a wheeled vehicle, the combinationwiththe axles, of Wheels journaled thereon and having grooved rims. wheel riins of greater diameter'and greater width than the road wheels and having tongues or ridges fitting the grooves of'the road wheels and having inner flanges, one of saidrims surrounding each road wheel, spoke-like arms on the outer face of'said rims carrying an axle pin, ablock for each Wheel in which said axle pin is journaled and means for carrying said blocks allowing it a limited longitudinal and vertical movement, substan-' tially as set forth.

In testimony whereof I aflix my signature, in presence of two subscribing witnesses.
